SHED-VENTILATOR.

t No. 901,120.

' specification of Letters Patent.

' Ap'pneationnlea my 6,1908. smal Ne. 431,139.

To all 'whom 'it may concern: i

Be it known thatI, FRANK J. NIEs, a citizen of the UnitedStates of America, and rcsiding at East Orange, in the county of Essex and State of' New Jersey, have invented certain new andl useful Improvements in Shed-ventilators, of which the following is' a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

lThis invention 4relates lto sheds and par-A ticularly tol train sheds as'employed at rail way stat-ions and terminals, and the object thereof is toprovide'means for' gases, vapors and vitiated air to pass outward into the openair and not permit rain, sleet or snow to pass therethrough beneath the shed; a further object being lto provideventilating means for shedsat present constructed' without a material change therein; a further object being to' provide lmeans whereby windsare prevented from enterinfy the said Ventilating devices and therebygtorce said gases, etc.rdownwardly, but which serve to deflect. the said windsand produce anv upward current of air through the Ventilating devices and thereby carry away the gases, etc. and a still further object being to provide such shed Ventilating devices which are simple in construction, comparatively inexpensive in installation and very economical in maintenance. gij;

My invention isfully describedrin the following specilication, of whichA the accompanying drawings form apart,l in which the separate parts are designatedby the same reference characters-in each of the views,

and in which Figure 1 is a section taken transversely through a train shed constructed according to my invention; Fig. 2 is a longitudinal section taken through one of the "Ventilating devices; and Fig. 3 is an enlarged, frag- .inentai-y, perspective view of one .of the Ventilating devices in position'. y

In the drawings forming a part of this application, I have shown a train shed a, com-v prising columns a2 and an arched roof a3' provided with a plurality Aof longitudinally arra cd air ducts a* over the tracks a5 and comp etely covering the platforms a, said roof `being; supported upon girders a7. At

.each side of each of the air ducts a* is a vertical apron b which extends entirely through the length of the shed, preferably,'or along that portion thereof occupied by trains or locomotives, said aprons extending both above and below the roof a3, as clearly shown, fora predetermined distance. Supported by a plurality of rods c, secured to the aprons b, is a longitudinally arranved cover c2 for each of the air ducts a,.havmg the under side outwardly flared from the center thereof in order to direct'the gases outwardly to each side thereof, said covers being of slightly greater width than the air ducts, and being preferably composed of reinforced concret-e', of cast iron, with or without a suitable filling or of any other desired material, calculated to withstand the corroding or action of the said gases. Secured to the rods c are al plurahty of outwardlyextending bars or brackets 0l which carry deiectors d2 for winds and arranged upon each side of each of the covers c2 and at a great 'enough distance `therefrom to permit the free passageof gases between said covers and detlectors and, in practice, I prefer to curve the said delectors upwardly and inwardly, and downwardly and outwardly in order to -so deflect the said winds as to cause ,a draft through the air ducts a4 and prevent the possibility of backdraft.

`It. will be seen that I provide a plurality of longitudinally arranged air-ducts directly over the locomotives and the trains and through vwhich rain, sleet or snow cannot pass because of the covers c2 although the said covers permit the free outward passage of gases through the air ducts, said covers beingcontinuous for the entire length of the air ducts, and in connection with which I also provide means yfor preventing rain and lthe like from being driven into the shed provided with my invention and for assisting the outward passage of gases and the like, these Wind deflecting means heilig also continued throughout the length of the air ducts and covers aft.

While but one form of air duct covers is shown, and but one form of the wind deiectors, it will be apparent that many modifications of the same may be madein order to accomplish the desired results and, reserving the right to all such changes in and modifications of the form shown and dcsciibed,

What I claim as new by Letters Patent, is:

1. In a shed, the combination of girders,

Patented Oct. 13, 1908.

and desire to securel a roof thereon, aprons extending through said roof and forming an air duct, and a cover arranged over said air duct.

2. In a shed, the combination of girders, a roof thereon, aprons extending longitudinally through said roof and forming an air duct and a longitudinally arranged cover -above said air duct.

3. In a shed, the combination of girders, a roof thereon, aprons extendmg through said roof and forming an air duct, a cover over said air duct and members connectedY with 5. In a shed, the combination of girders, a

roof thereon, provided with a longitudinally arranged opening therethroughz vertical apronsv at each side of said openm and a cover for said opening carried by sai aprons at a distance thereover.

6. In a shed, the combination of girders a roof thereon and provided with a longitu inall arranged opening therethrough, a vertica apron at each side of said opening and forming an air duct, a cover for said duct at a distance above said a rons and formin side openings, and wind eflectors arranged before said side openin 7. lIn a shed, the comination of girders.. a

` roof thereon, vertical aprons through said roof forming an air duct, a cover above said an' .duct and formlng slde openings, and

. wind deflectors before said side openings,

said deflectors' being downwardly and outwardly flaredkgl.v

8. In a shed, the combination of girders, a. roof thereon and provided with a longitndiv nally arranged' opening therethrough, a

cover at a distance above said opening and forniin side openings, and u wardly and inward y flared deflectors in ront of said side o nings.

9. n a shed, the combination of girders a roof thereon and provided with a longitu nally arranged opening therethrough,l a cover at a distance above said o ning and forming side openin and de ectors, up wardly and inward flared and downwardly and outward y flared, before said side openings.

10. In a s ed, the combination of girders, a roof thereon and provided with a longitudinally arranged opening therethrou h, a

cover, upwardly and outwardly flared, a ove said opening and forming side o enin and means for preventing entrance o win s into said side openings,

11. In a shed, the combination of girders, a roof thereon and provided with a longitudinally arranged opening therethrough, a cover, upwardly and outwardly flared in two directions above said opening and forming side openings and means for'preventing the passa o fwinds into said side openings.

12. n a shed, the combination of girders, a roof thereon and provided with a longitudinally arranged opening therethrou h, a cover, upwardly and outwardly flared, a ove said opening and deflectors, inwardly and outwardly curved, at each side of said openmg.

13. In a shed provided with aA longitudinally arranged opening throu h the roof thereof.; a longitudinally arran cover upwardly and outwardly flaredgeabpve said opening.

In testimony that I claim the foregoing as my invention I have si ed my name in presence of the subscriblng witnesses this fifth day of May, 1908.
